CARL F. GERLIN'GEB, 01? DALLAS, OREGON.

To all whom it may concern:

Be it known that I, CARL F. GERLINGER, a citizen of the United States, residing in Dallas, in the county of Polk and State of Oregon, have invented certain new and useful Improvements in Bunks and Locking- Blocks for Logging-Cars, of which the following is a specification.

This invention relates to that part of a logging car known as the bunk which supports the logs and which is equipped with chocks for holding the logs in place on the bunks. It is customary to so mount the chocks in the bunks that they may be low ered to release the logs when the car is dumped, and various arrangements have been suggested for raising and lowering the chocks for this purpose.

According to my invention I provide a log bunk with improved chocks and novel chock-operating devices of simple and durable construction which may be operated from the side of a car opposite that from which the logs are delivered and which, when in proper position, hold the logs securely but when lowered are entirely withdrawn from the logs, thus permitting them to be readily discharged.

In the accompanying drawings :Figure 1 is a perspective view, showing the outline of a logging car with my improvements applied. The remaining figures are on an enlarged scale. Fig. 2 is a detail view, partly in elevation and partly in section, and with parts broken away, showing how one of the chock blocks is mounted and operated in a bunk. Fig. 3 is a perspective view of one of the chock blocks. Fig. 4 is a perspective view of one of the links employed in connection with each chock block. Fig. 5 is a detail view, in section, on the line 5-5 of Fig. 2.

The outline only of a logging car A is shown, but my improvements may be applied to cars of various construct-ion. Each bunk B consists of two ordinary railroad rails b placed side by side and secured to the platform of the car. At each end of each pair of rails I mount a chock block C, which is arranged between the rails of the pair and is pivotally connected at one end with them. At its opposite end each block is pivotally connected with one end of a link D, the opposite end of which is provided with laterally projecting arms d, for a purpose hereinafter described. Each block G is formed Specification of Letters Patent.

with laterally projecting arms 0 and an opening extends through the arms and block to receive a bolt E which also extends through the rails and thus pivotally connects the block with the rails. Each block is formed with a recess 0 to receive one end of a link D and a bolt or pin F pivotally connects the link with the block.

The arms (I of the link D enter recesses cl in the ends of the rails, as clearly shown in Fig. 2. When a block is set for holding the logs the parts are in the position illustrated, with the arms (Z in the recesses d, but when the arms (Z are withdrawn from the recesses (Z the block and link drop into the position shown by dotted lines in Fig. 2.

It will be understood that there is a chock block at each end of each bunk and each of the blocks is of the construction shown, and is pivotally connected with a link. outer end (Z of one of the arms (Z of each link engages the hooked end (1 of a rod G which extends along the outside of one of the rails b and may be guided by wire guides II. The end of the rod G, opposite to its hooked end, has attached to it a downwardly extending arm I which is provided with a laterally extending arm i that extends through a bar J pivotally connected by a bolt K to the car frame. A cotter-pin L prevents the separation of the bar J from the arm I. WVhen the parts are in the position shown in the drawings, with the hook g engaging the arm (Z and with the arm I engaged with the bar J the check is held in the position shown by full lines in Fig. 2.

\Vhen it is desired to unload the car, the chock may be lowered by withdrawing the cotter-pin, swinging the bar J clear of the arm 2' and then the rod G may be moved outwardly, the arms (Z released from the recesses d, and the link D and block C will drop to the position shown by dotted lines. All of the chocks are operated in a similar way, and it will be observed that the blocks can only be released from that side of the car opposite to the side where the chocks to be lowered are located. In order to restore the chocks to their operative position, it is only necessary to raise the blocks with the links and place the arms (Z in the recesses ll, engage the hooks g with the arms and engage the arms I with the rods L in the manner before described.

It will be observed that I employ ordinary railway rails and that the parts of the durable: V and.
